This morning we brought you the recording of the concert that Radiohead offered last Friday at the Bonnaroo Music & Arts Festival. Yesterday the band repeated the performance in Chicago, and among the songs that were played there was room to debut a new song, “ Full Stop”. In the words of Thom Yorke, it’s a song that “improves over time, like a good wine” . As was to be expected, the fans quickly uploaded their recordings of the moment to YouTube.
